For me it is the biggest opportunity for all of us,because it can change our live from nothing into something great,i start with few bucks now i am holding quarter a million dollar in just a year,which is why i am strongly agree that cryptocurrencies could start a good future for all of the early adopters like us,though it isnt late for those who are planning to invest it is better for us to stick with these coin as it can these currencies can replace fiat in the future.
